Freelancer Overview

I possess extensive experience in the full lifecycle of AI data preparation, specializing in the creation of high-quality datasets for Large Language Models (LLMs) and Computer Vision systems. My expertise encompasses designing precise annotation guidelines, executing complex data labeling (including NER, sentiment analysis, and semantic segmentation), and performing rigorous data cleaning to ensure model accuracy. I am adept at managing the transition from raw data to model-ready inputs, consistently maintaining high inter-annotator agreement scores through meticulous quality control processes.
